This was all known. The cruz supporters just chose to ignore it just like they are cruz's indiscretions.
Trump donates to democrats: ignored
From Politifact:
Trump has actually been relatively evenhanded in doling out cash to the two parties, but since 1989, he’s contributed over $350,000 more to Republicans running for federal and state offices, campaign finance records show.
Data from the Federal Election Commission and state elections offices provided by the two websites show that Trump has given $584,850 to Democrats and $961,140 to the GOP over the last 26 years.
The difference in donations is almost entirely captured in Trump’s recent giving. Since 2012, Trump has donated $463,450 to Republicans and just $3,500 to Democrats (California Attorney General Kamala Harris and New York Assemblyman Michael Benedetto).
Trump says he's for the assault weapons ban: ignored
The only very mild restriction Trump advocated was in 2000. A myriad of strong statements through the years confirm to all but the partisan payers looking for an ax to grind that Trump is very strongly for the 2nd Amendment.

For assault weapon ban, waiting period, & background check
I generally oppose gun control, but I support the ban on assault weapons and I support a slightly longer waiting period to purchase a gun. With today’s Internet technology we should be able to tell within 72-hours if a potential gun owner has a record.

Trump says he's very pro choice: ignored
Again we need to travel back to 1999 for any support for your statement, within months of that interview where Trump was backed into a corner and gave a weak assent Trump repudiated his position publicly. Trump's growth into a strong prolife advocate began in 2000 and has continued without any equivocation or backsliding. Why not let the man's statements speak for him?

Trump pals around with the Clintons: ignored
This is not worth debunking, they were in the same circle and were cordial before Trump entered the political arena.
Trump loves him some eminent domain: ignored
Eminent Domain is the law of the land. It is necessary but needs better limitations IMHO. Trump did not abuse the laws and the town councils made the decision that they wanted to invite projects to revitalize their town and enhance the tax base. Work to change the law or hold town councils responsible to have referendum.
Trump brags about his indescretions: ignored Seems to be a theme. The theme is you don't like Trump, your right to your opinion. But if you try to slander him with inaccurate accusations I'm going to put the links to the truth out there so people can make up their own minds.
